The Vestmarka trail map is one of four special maps at a scale of 1:20 000 covering Oslomarka. The map has been prepared in close cooperation with the Ski Association. The map series is tailored for winter use and covers more than 3,000 kilometers of groomed ski trails.
Each map clearly shows trail types and distance information, as well as practical extras such as parking lots, cabins and refreshment points. The information is adapted for easy coordination with real-time information on the Ski Association's website. The maps are based on terrain data from laser scanning from aircraft, which ensures outstanding accuracy in detail.
